BAG-ASTENER.

Patent-ea nag. a, iam.

Application filed June 9, 1916. Serial No. 102,636.

ers, and has reference more particularly to a A fastener which constitutes reinforcing means at the mouth of the bag. The ob]ect of the invention is to provide a simple and ineX- pensive bag fastener which is rigid, durable, and which does not permit the side of the bag to buckle.

With the above and other objects in View, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts .as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of an open paper bag embodying my fastener;

Fig. 2 is a similar view showing the mouth of the bag covered b v the flap and the flap ready to be engaged by the fastener;

Fig. 3 -is a perspective view of the upper part of the bag showing the bag fastener;

Fig. 4 is a perspective view of the upper part of the bag when seen from the other side from that shown in Fig. 3;

Fig. 5 is an enlarged vertical section through the bag when closed on line 5-5, Fig. 3; and

Fig. 6 is a plan view of the bag blank.

Referring to the drawings, 7 represents a blank suitable 4to be folded into 4a bag presenting at one end thereof a mouth through which merchandise may be introduced thereinto. At the edges which are to form the mouth the blank is provided with a tongue 8 and a flap 9. Both may form an integral part of the blank, as shown in Fig. 6, or they may be pasted thereto. The flap 9 is to fold over the mouth of the bag along the base thereof, that is to say, on lines a-a (see Fig.l 6). The tongue 8 is folded along its base on line 7)--5 against the exterior surface of the side of which it forms part.

The end of the tongue 8 carries a pliable,

`metal strip 10, preferably' secured thereto by wrapping the end portion of the tongue about the strip, the extremity of the strip proj ectn'g out of the tonguefbeyond the longitudinal edges of the back. The metal strip 10 is so secured to the tongue 8 as to have clearance from the edge of the flap 9 and fold against the flap 9.,;when the same is folded over the tongue vf8 (see Fig. 2). The flap and tongue are further folded to interlock, as shown in Figs. 3 and 5 whereby the tongue 8 and flap 9r will bie folded on lines 0 0. The projecting ends of the strip can then be bent `against the other side of the bag, as shown' in Fig. 4, thus locking the mouth of the bag positively, the strip serving as a reinforcing member for the bag at the mouth. It 'will be noted that the bag is locked slightly below the mouth thereof and the edges .or corners at the mouth are prevented froth-'spreading by the engagement of the ends' of the strip with the edges of the bag. Thus, a sudden shift of the contents within the bag cannot open the bag.

Preferably a portion of the tongue 8, bound by the base line b-b and the fold 0 0, may be secured to the bag with glue. That portion only serves as means for extending the metallic'strip sufficiently from the edge of the mouth of the bag to form a clearance between the metallic strip and the edge of the flap 9. By gluing the portion o f the tongue 8 bound by the lines b b, c-c, the bag will be reinforced at the mouth by the said portion of the tongue.

I claim:

A bag of the class described having a tongue' on one side of the bag depending from the mouth, a flap forming a part of the bag adapted to fold over Ithe mouth and tongue without folding the bag proper at the mouth, and a foldable metallic strip secured to the free end of the tongue, the eX- tremities of the strip projecting beyond the edges of the bag, said flap and tongue being adapted to be rolled about the strip toward the mouth of the bag when the bag is to be sealed, the projecting ends of the strip being adapted to be folded over the adjacent edges of the bag and lock the folded tongue and flap to the bag.
